Based on the following factors, subgroup analysis was done to evaluate the relationship between DUXAP8 expression levels and OS: follow-up time (<60 or ≥60 months) (Figure 2A), the system of cancer (digestive system, urogenital system, respiratory system, hematologic system or other) (Figure 2B), sample size (<100 or ≥100 tissues) (Figure 2C), sample source (clinical samples or database) (Figure 2D), the quality of included literature (NOS scores) (Figure 2E), and type of cancer (Figure 2F). Here, DUXAP8 is linked to cancer.
